Hey, so I won´t say that but
shame on you :P
If you are familiar with c++ the bash script should be just simple.
Shows that it is a shell script and tells the OS to invoke the specific shell - here
sh.
Code:
usage () {
exec 1>&2
while [ "$#" -ge 1 ]; do echo "$1"; shift; done
cat <<USAGE
Usage: ${0##*/} [OPTIONS]
Options:
-i | -interface no refinment in vertical direction of the mesh
-l | -local mesh with local refinment
-h | -help help
Ship hull simulation to demonstrate two different meshing strategies that can be
used with PLIC type schemes.
USAGE
exit 1
}
This is a function definition. It will show the options you can use with the script such as:
Code:
~: ./Allrun -i
~: ./Allrun -l
~: ./Allrun -h
The other parts in the above code can be checked out using
google or any search engine.
Code:
meshType=0
# OPTIONS
while [ "$#" -gt 0 ]
do
case "$1" in
-i | -interface)
meshType=1
break
;;
-l | -local)
meshType=2
break
;;
-h | -help)
usage
;;
-test)
shift
;;
-*)
usage "Invalid option '$1'"
;;
*)
usage "Invalid option '$1'"
break
;;
esac
done
Here we define a variable named
meshType and loop through a while loop if you added a parameter to the script, e.g.,
Allrun -i or
Allrun -l. If you call
Allrun -h you will call the
usage function. If you call any other non-sense such as
Allrun -foobar or
Allrun noneSense you call the
usage function while sending the parameter $1. The $1 includes the parameter you added to the Allrun script call. This parameter is used in the function
usage later on (if needed). If you just call
./Allrun (without parameter) the
meshType has the value zero.
Code:
# Run from this directory
cd "${0%/*}" || exit 1
# Source tutorial run functions
. "$WM_PROJECT_DIR/bin/tools/RunFunctions"
Should be obvious with the two comments
Code:
if [ $meshType -eq 0 ] || [ $meshType -eq 1 ]; then
{
./Allmesh.1
}
elif [$meshType -eq 2 ]; then
{
./Allmesh.2
}
fi
Depending which input you specified, you execute either the first or second script for meshing. The rest is just calling OpenFOAM applications:
Code:
runApplication setFields
runApplication decomposePar
runParallel $(getApplication)
runApplication reconstructPar
$(getApplication) is defined in the
RunFunctions script we load in prior. However, you question is not related to OpenFOAM at all and is just a bash scripting question - was not expecting people who say

ask such questions :) - okay. bash is sometimes a bit wired to read but, hey, you seem to be a programmer so its common that things look strange ;)
Hope this was enough information and I was just kidding with the
shame on you sentence :)
